Conference onDecentralised Wastewater
Management in Asia
Meeting urban sanitationchallenges at scale
20 – 22 November 2012 • Nagpur, India

In co-operation with:
Conference OutlineThe world is facing immerse challenges arising from rapid population growth and intense urbanisation. In Asia, about 45% of the population now live in towns and cities, and by 2030 it is estimated that this will reach 55%. Population densities in Asian cities are much higher than other parts of the world, and the predominance of poverty in urban slums is ubiquitous throughout the region.
Against this backdrop, the lack of wastewater management continues to be a huge challenge. Conventional centralised approaches to wastewater management have largely failed to address the wastewater disposal needs of poor communities due to high capital investment, poor operation and maintenance or low connection rates. As a result, many urban dwellers remain unserved with basic sanitation and the vast majority of wastewater and septage is discharged without any form of treatment into rivers and water bodies, seriously polluting water resources and causing a diversity of economic impacts.
As a result of this crisis, demand for a�ordable but e�ective wastewater management systems is increasing and there is a growing body of science and practice which demonstrates the opportunities for implementing wastewater management systems based on a decentralised approach. The decentralised approach – referred to as DEWATS - has been demonstrated to be a cost-e�ective and e�cient way of wastewater treatment to improve environmental health conditions as well as providing opportunities for re-use and resource recovery. Decentralised approaches also o�er increased opportunities for local stakeholder participation in planning and decision-making.
The objective of this Conference is to build capacity and awareness of DEWATS as a viable sanitation option for countries in Asia to enhance sanitation coverage and service delivery in the urban environment and provide a cost-e�ective means for treating wastewater. It will focus on (a) sustainable technical options, (b) management options and the roles of various stakeholders, and (c) enabling institutional and regulatory frameworks for the e�ective implementation and scaling-up of decentralised systems.

DEWATS For Vocational Training Centre, Lonara, Nagpur, MaharashtraThe Vocational Training Centre at Lonara, Nagpur, comprises of a training centre and hostels, accommodating around 110 persons. In order to overcome the water shortage problem, and also to demonstrate the treatment and reuse of domestic wastewater, a DEWATS unit was imple-mented by the Indian Institute of Youth Welfare, Nagpur. This project commissioned in 2004, was funded by BORDA. CDD Society provided technical support in design and implementation. S.N Architects supported the implementation process. The DEWATS unit has a treatment capacity of 20m3 per day. This unit treats domestic wastewater from the campus (canteen, toilets, bathrooms and wash areas). The construc-tion of this unit took 8 months. The unit comprises of 8 primary treatment modules – settlers for each block of the campus. The outflow from the settlers is connected to a baffle reactor which acts as the secondary treatment facility. Tertiary treatment takes place in a planted gravel filter. The treated effluent is collected in a tank from which it can be reused for gardening and horticulture and the sludge is used as compost. The effluent quality assessment indicates an overall organic load reduction of 80%.
DEWATS At Public Toilet In Kalmeshwar, NagpurKalmeshwar Municipal Council in its efforts to provide better sanitation facilities and a cleaner environment agreed to implement a DEWATS unit for a public toilet complex at a vegetable market in Kalmeshwar. The Toilet complex is having facilities of urinal, bathroom and toilets both for men and women. This toilet complex is maintained by a private contractor on pay and use basis.
This project, commissioned in 2011, was funded by Kalmeshwar Municipal Council. The treatment capacity of the DEWATS unit is 12 m3 per day. Operation and maintenance of the toilet complex as well as the DEWATS unit is carried out by the Municipal Council. The DEWATS unit comprises of a settler, anaerobic baffle reactor, anaerobic filter and a planted gravel filter. The area around the toilet complex has been developed as a garden. The treated wastewater is reused for gardening, pathway washing and flushing in toilets.
DEWATS For Mahajan Nagar Community Mahajan Nagar is a slum situated along Sonegaon Nallah on Beltarodi road in Nagpur. There are around 166 households, each planned in plot sizes of 450 and 600 sq ft. Around 50 % of the houses in the area are constructed as a temporary shelter with no proper sewage systems. DEWATS was introduced to this community by Indian Institute of Youth Welfare with the funding support from BORDA, local Gram Panchayat and Municipal Corporation along with the technical support of CDD Society and S.N. Architects. The project helps in the safe disposal of treated wastewater along with improving the environmental and hygienic conditions.
The DEWATS unit built in an area of 820 m2 treats domestic wastewater from the toilets, kitchen, and wash-area of the houses in the commu-nity. The DEWATS unit also provides partial treatment for domestic wastewater that is tapped from the drain coming from the upstream localities. Therefore this treatment unit, in addition to treating the wastewater generated from the Mahajan Nagar community also reduces the pollution burden by providing partial treatment to the wastewater flowing in the drain collecting wastewater upstream of this settlement. The DEWATS unit at Mahajan Nagar was constructed in two phases, the first phase having only a settler as primary treatment (capacity - 575 m3 per day for 5000 users) and the second phase (capacity - 40 m3 per day for 800 users) having baffle reactor as secondary and planted gravel filter as tertiary treatment process. The treated wastewater is collected in a tank from where it is reused for landscaping and gardening of the community area. The plant is operated by trained personnel from Nagpur Municipal Corporation. The plant shows a treatment efficiency of 95% in terms of removal of organic load.
